GEORGE R. VVlGHT, OF NEl/V YORK, N. Y.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 249,714, dated November15, 1881.

Application filed August 8, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. YVIGHT, of the city, county, and StateofNew York, have invented certain newand useful Improvements inRefrigerators, of which the followng is aspecification.

Myinvention relates torefrigerators in which the ice-chambercommunicates directly with the provision-chamber, and also indirectly bymeans of a number of tubes which extend from the ice-chamber downwardand are filled with ice.

The object of my invention is to increase the cold-radiating surface insuch a refrigerator, and thus obtain better effects.

The invention consists in the combination, in a refrigerator, with theice-chamber, the provision-chamber communicating directly with saidice-chamber, and tubes leadin g down ward from the ice-chamber, ofair-tubes arranged within the tubes first mentioned, leaving annularspaces between said tubes which may be filled with ice, and annularopenings between said tubes at their lower ends, whereby provision isafforded for the passage of air from the ice-chamber downward throughthe inner tubes and between the inner and outer tubes. The inner tubesare preferably bent or continued horizontally outward at their upperends, and communicate directly with the upper part of theprovisionchamber, so as to take air direct therefrom.

In the accompanying drawings, Figure 1 represents a vertical section ofmy improved refrigerator, and Fig. 2 represents a horizontal section onthe dotted line 00 a, Fig. 1.

A designates the provision-chamber of the refrigerator, and B designatesthe ice-chamber, which is in the upper part and at one side of therefrigerator. The refrigerator is formed of sheet metal in the ordinaryway, but the wooden box or case by which the metal case is surrounded ishere omitted. The air-chamber B isseparated from the provision-chamberby a partition, a, in which are holes 0, which place the two chambers indirect communication, and the two chambers are provided with doors A B,through which the ice and provisions are introduced. In the lower partof the ice-chamber B is a removable ice-bunker, 0, into which all thewater drains, and which can be readily removed for cleaning. So far asthe present invention is concerned, how'- ever, the ice-bunker need beregarded only as a part of the ice-chamber.

Extending from the bottom of the ice bunker or chamber are a number oftubes or pipes, D, open at both ends, and below said tubes or pipes isplaced a drip-pan, E, which receives the water formed by the meltingice.Each of the tubes or pipes D is slipped over a nozzle or rigid section,D, upon the ice-chamber, and is provided at the lower end with feetwhich rest in the drip-pan E. Wheneverit is desired to remove the panall the tubes or pipes D may be slipped up upon their nozzles or rigidsections D, thus raising their lower ends out of the drip-pan.

F designates air pipes or tubes, which are smaller in diameter than thepipes or tubes D, and are arranged inside the latter. The pipes or tubesF extend upward through the icechamber B, nearly to the top thereof, andare bent or continued horizontally toward thepartition a, through whichthey pass, andin which they are secured. Thelower ends of the innerpipes or tubes, F, are also represented as bent or continuedhorizontally toward the middle of the provision-chamber, so that thecooled air will be directed in that direction. The 8opipes or tubes Fare made of sheet metal, and may each have one or more slip-joints, b,to enable them to be readily inserted in place and removed.

It will be observed thatannular spaces are formed between the outer andinner tubes, D and F, and also annular openings between said tubes attheir lower ends.

The pipes or tubesFmightbe perforated for apart or the whole of theirlength, if desired. 0

In the operation of my refrigerator the annular spaces between the innertubes, F, and

the outer tubes, D, are filled with broken ice, and the exteriorsurfaces of the outer tubes and the interior surfaces of the inner tubes5 form radiating surfaces for cooling air, while air which enterstheice-chamberthrough holes 0 is cooled by direct contact with the icein passing downward between the outer and inner tubes, and passes outatthe annularopen- 10o ings between the tubes at their lower ends.

It will be seen that the cold-radiating surface is greatly increasedbytheinner air-tubes, and that therefore a cooler atmosphere can bemaintained in the provision'chamber.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The combination, in a refrigerator, with the ice-chamber, theprofision-charnber communicatingdirectly with said ice-chamber, andtubes leading downward from said ice-chamber, of air-tubes arrangedwithinthetubes first mentioned, leaving annular spaces between saidtubes which may be filled with ice, and annular openings between saidtubes at their lower ends, whereby provision is afforded for the passageof air from theice-chamber downward through the inner tubes and betweenthe inner and the outer tubes, substantially as and for the purposespecified.

the passage of air downward through the tubes 0 F, and between the tubesD and F, substantially as and for the purpose specified.
